Abstract
A probe useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical cavity generally comprises a chassis with an electrical connector extending from the proximal end of the chassis and terminating at a plug configured for connection to a pulse oximeter box. The probe further includes an optics assembly configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. The probe further includes a deployment device attached to the chassis for biasing the optics assembly into the tissue wall of the anatomical canal and stabilizing the probe within the canal. Further, the oximetry sensing assembly may be configured as part of an esophageal stethoscope having other sensing devices, for example, a temperature sensor, a pacing assembly, and an acoustic monitor.
